R410A REFRIGERANT

R410A refrigerant has a higher operating pressure in comparison to R22 refrigerant and, therefore, all piping system
materials installed must have a higher resisting pressure than the materials traditionally used in R22 systems.
R410A refrigerant is an azeotrope of R32 and R125, mixed at 50:50, so the ozone depletion potential (ODP) is 0.
WARNING
Do not place the refrigerant cylinder in direct sunlight. Refrigerant cylinder may explode causing severe injury
or death.
Note:
Because R410A is a combination of R32 and R125, the required additional refrigerant must be charged in its
liquid state. If the refrigerant is charged in its gaseous state, its composition changes and the system will not
work properly.
Do not heat piping more than necessary during installation. Piping may become soft and fail when
pressurized.
Do not use any piping that has not been approved for use in high-pressure refrigerant systems. Piping wall
thickness must comply with the applicable local, state, and federal codes for the 551 psi design pressure of
R410A. Inadequate piping may fail when pressurized.
